Hello Bill, Thank you very much by your suggestion with respect to my problem.
Now I have modified the code of the file vpopmail.c and in addition I have added a new file pop3.cdb. Perhaps it is good for implementing this option in the next versions of the vpopmail package. I think that the option of ALLOWROAMING seems a good option to have a better control of roaming. Again, Thank you very much. These were my modification: file vpopmail.c #ifdef POP_AUTH_OPEN_RELAY int open_smtp_relay() { char *allowroaming; allowroaming = getenv("ALLOWROAMING"); if(allowroaming == NULL){ return(0); } create the new file : /usr/vpopmail/etc/tcp.pop3 192.168.:allow,ALLOWROAMING="" this is my file /var/qmail/supervise/qmail-pop3d/run #!/bin/sh VPOPMAILUID=`id -u vpopmail` VPOPMAILGID=`id -g vpopmail` exec /usr/local/bin/tcpserver -l 0 -R -H -v \ -x /usr/vpopmail/etc/tcp.pop3.cdb \ -u"$VPOPMAILUID" -g"$VPOPMAILGID" 0 110 \ /var/qmail/bin/qmail-popup kerberos.qnet.com.pe \ /usr/vpopmail/bin/vchkpw \ /var/qmail/bin/qmail-pop3d Maildir 2>&1 Before, execute this command. tcprules /usr/vpopmail/etc/tcp.pop3.cdb /usr/vpopmail/etc/tcp.pop3.tmp < /us r/vpopmail/etc/tcp.pop3 Do you have another idea for this topic? ----- Original Message ----- From: "Bill Shupp" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Subject: Re: [vchkpw] Deny the option Roaming-User the a specific Pool of IP Ok, upon rereading your post, I see that I answered a different question.. ; ) What you are asking for could be done pretty easily, I think. Just setup another rules file, like tcp.pop, and add a rule like so: 1.2.3.:allow,ALLOWROAMING='"" This says that only addresses in 1.2.3.0/24 are allowed to roam (assuming that the the NO_RELAY bit is not set for the user). Then, in apply this patch to vpopmail.c: *** vpopmail.c.orig Tue Aug 20 21:34:34 2002 --- vpopmail.c Tue Aug 20 21:37:39 2002 *************** *** 2040,2045 **** --- 2040,2050 ---- #ifdef POP_AUTH_OPEN_RELAY int open_smtp_relay() { + allowroaming = env_get("ALLOWROAMING"); + if(!allowroaming) { + return(0); + } + #ifdef USE_SQL vopen_smtp_relay(); update_rules(); That should prevent roaming users for any ip's that don't have ALLOWROAMING set. *Note that this hack forces you to specify which ranges can roam, and prevents roaming by default. Also, I haven't tested this, but it does compile. So your mileage may vary... ; ) Regards, Bill Shupp
